IMPROVEMENT IN SPlNNlNG-LATHES.

Specification forming part of Letters Patent No. 177,044, dated May 2, 1876 application filed January 28, 1576.

To all whom it may concern Be it known that I, ULRIcH WAssMER, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Lathes, of which the following is a specification:

My invention relates to lathes or other machines which require a ready means of adj ustupon a mandrel of eorrespondingtbrm; also,

in a ready means of attaching and detaching the work to or from the centers between which it is spun.

In the accompanying drawings, Figure 1 is a longitudinal elevation of a lathe, with my invention shown as attached to the tail-rest,

Fig. 2 is a transverse section of the same, showing the leverage and weight by which means pressure is brought to bear upon the work while between centers; and Fig. 3 is a partial sectional plan of the tail-rest, showing the slotted sleeve and kn tickle-jointed lever attached thereto.

In the annexed drawing, A represents the shears of a lathe, upon which are mounted the usual head-rest B, tool-rest G, and tailrest D. Firmly attached to the tail-rest D is a slotted sleeve, E, in the slot F of which works a knuckle-jointed lever, a a a? a fulcrumed to the sleeve E at G, and jointed to the sliding eenterH at I .by means of lovers a a and a 0,

which meet at and join with red j at K. Attaehed to and descending from the slotted sleeve E is a treadle-support, L, which is constructed to move with the tail-rest D and sleeve E. 'lhe treadle d d d is fulcrunled to the support L at d, and attached to its end (Z is a suitable weight, 0. The rod j being attached to the aforesaid treadle at f, and to the knucklejointed lever at K, causes the sliding spindle and its attached center H to move in or out as the weight 0 is allowed to descend, or as
